Astronomers have found a star that's only as hot as a cup of coffee, making it a candidate for the coldest star known. That is, assuming it's a star. While a cup of coffee may sound hot — the ...

This post is not about short people of a particular color, who are ill. This is about Brown Dwarfs. You likely know of them as the stars that are forever stuck in puberty – too massive to be ...

All three brown dwarfs spotted in the Perseus region by Webb have surface temperatures ranging between 1,500 and 2,800 degrees Fahrenheit (830 and 1,500 degrees Celsius), a hell of a lot less than ...

Brown dwarfs are poorly named: they’re not really brown. They’re objects that are too small to really be called stars; they lack the oomph needed to fuse hydrogen into helium in their cores ...

Brown dwarf stars exist somewhere between giant gas planets, ... Despite the name "brown dwarf", these objects cool and change over time, and therefore do not have a definitive color.

Well this brown dwarf has aurorae that are at least 10,000 times more powerful than Jupiter’s aurora.” The aurorae’s colors are also a bit more diverse, emitting red along with blue and green.

Brown dwarfs are objects that straddle the dividing line between stars and planets. ... (Near-Infrared Camera) to identify brown dwarf candidates from their brightness and colors.

They separated the object’s light into individual colors to form its spectrum, ... This brown dwarf is far too cold for its ambient temperature to be the energy source exciting the methane.

These stars, also known as brown dwarfs, are mysterious objects with more than 12 times the mass of Jupiter and less than half the mass of the sun. Scientists have long debated whether these ...

Astronomers recently discovered two brown dwarfs in our solar neighborhood, and they’re actually pretty close by: 15 and 18 light years away! [Click to hugely unendwarfenate.] The two objects ...

In this brown dwarf's case, both the source of the particles and the color of the aurora has sparked theories. The aurora seen was red, indicating that the atmosphere mostly consisted of hydrogen.

Still, a brown dwarf would have enough of a gravitational pull to explain the odd orbit in V471 Tauri. Until recently, however, it was impossible to actually look for the dwarf, as they are very ...
